How to set the JAVA_HOME in Mavericks 10.9?

Question

I checked the java it is installed on my system.If i enter whereis java it shows me the

/usr/bin/java

I want to set the JAVA_HOME, i already gave the path /Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk/Contents/Home but it won't work.

If i enter $JAVA_HOME it returns nothing.

If i enter this command /usr/libexec/java_home -v 1.7 it shows me the result

/Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk/Contents/Home

but while setting up my local workspace it won't work it simply says

`/Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk/Contents/Home` is not valid `JAVA_HOME`

How can I resolve this issue?

Environment variables such as this are stored in bash and users use configuration files to set parameters for their bash environments.

for example in your home directory you will likely have one or both of a .bashrc or a .bash_profile file.

1) open this file

vi ~/.bash_profile

2) add the following line to this file

#Default to java 1.6
export JAVA_HOME=`/usr/libexec/java_home -v 1.6`

This will set the $JAVA_HOME variable to the path defined above. In my case:

/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

Once you change a bash configuration file you either need to restart your terminal or source that file

source ~/.bash_profile

Then finally confirm that this worked by running the command

echo $JAVA_HOME

You need back ticks otherwise it will save the string as the environment variable. Also the spaces will throw erros – Chris Thompson Jun 20 '14 at 18:32
There are back ticks in the answer... and I tested it with the spaces and they work as long as they are contained within the back ticks – pwilmot Jun 20 '14 at 18:37
@pwilmot Yep! I think it was because of the original formatting they didn't show up. Looks good now! – Chris Thompson Jun 20 '14 at 18:42
@AdalarasanSachithanantham after following the steps when you enter echo $JAVA_HOME into a terminal nothing shows up? – pwilmot Jun 20 '14 at 19:09
once i followed the steps it shows me the path..but if i close the terminal and open it again...It doesn't shows anything. – Adalarasan Sachithanantham Jun 20 '14 at 19:22
